CC   -!- FUNCTION: Strong activator of the late viral genes promoters. Enhances
CC       the expression of the capsid protein and nuclear shuttle protein. Acts
CC       as a suppressor of RNA-mediated gene silencing, also known as post-
CC       transcriptional gene silencing (PTGS), a mechanism of plant viral
CC       defense that limits the accumulation of viral RNAs. Suppresses the host
CC       RNA silencing by inhibiting adenosine kinase 2 (ADK2), a kinase
CC       involved in a general methylation pathway. Also suppresses the host
CC       basal defense by interacting with and inhibiting SNF1 kinase, a key
CC       regulator of cell metabolism implicated in innate antiviral defense.
CC       Determines pathogenicity (By similarity). {ECO:0000250,
CC       ECO:0000269|PubMed:10570213, ECO:0000269|PubMed:15919897}.
CC   -!- SUBUNIT: Monomer. Homodimer. Homooligomer. Self-interaction correlates
CC       with nuclear localization and efficient activation of transcription.
CC       Monomers suppress local silencing by interacting with and inactivating
CC       host adenosine kinase 2 (ADK2) in the cytoplasm. Interacts with and
CC       inhibits host SNF1 kinase. Binds to ssDNA (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000250}. Host cytoplasm
CC       {ECO:0000250}. Note=The phosphorylated form appears to accumulate
CC       almost exclusively in the nucleus, whereas the non-phosphorylated form
CC       is found in both nucleus and cytoplasm. {ECO:0000250}.
CC   -!- DOMAIN: The zinc finger and the transactivation region are involved in
CC       PTGS suppression.
CC   -!- PTM: Phosphorylated. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the geminiviridae transcriptional activator
CC       protein family. {ECO:0000305}.
